This is like the same rules as the Sergio Thompson vs. Jorge Linares fight had. If Linares beat Thompson he would go on to rematch DeMarco. If Thompson wins he would be ignored by the WBC. Same with Ortiz-Lopez just it's Golden Boy. If Ortiz beats Lopez he goes on to fight Canelo. If Lopez beats Ortiz he will be ignored his shot to Canelo by Golden Boy. A shot at Canelo only applies to Ortiz as it did in the Thompson-Linares fight.
Lopez is also a bit small. Ortiz is more of a WW than a SWW. I don't expect Lopez to beat Ortiz either. I doubt he wins a clear round. Ortiz will be much bigger than him on fight night. Victor Ortiz is not Jessie Vargas.
